Condition Monitoring and Fault Diagnosis for Hoisting System Driven by PMLSM

The hoist system driven by Permanent Magnet Linear Synchronous Motor (PMLSM) is a revolutionary new technology for high-rise buildings and ultra-deep mine, but also requiring new technology to enhance reliability and improve customer service. Condition monitoring (CM) is a technique or a process of monitoring the operating characteristic of a physical system. By studying on the structure and operating characteristics of PMLSM driven hoisting system, the paper proposes an on-line condition monitoring system for PMLSM driven hoisting system, which can monitor the operation parameters, give faults have occurred, and identify the root cause of the fault. The fault models and condition monitoring soft are designed. The obtained results are expected to be useful for PMLSM driven hoisting system.
